After expanding the capacity by widening the trolley of the No.3 sintering machine,severe uneven sintering occurred in the trolley’s lateral distribution,which affected the output and quality of sinter.In this study,the quantitative evaluation indices of the burden uniform distribution in the width direction of the sintering machine is introduced for the first time.By measuring the temperature of discharged gas,a plane temperature field is constructed.Through analyzing the temperature field and the burden layer’s differential thermal equilibrium,a mathematical model for evaluating the indices,which is an online reflection of the degree of uniform distribution,is built.Following the improvements in burden distribution equipment,the optimization of the ignition system and the dynamic adjustment of the process,the problem of uneven sintering in lateral distribution has been solved,and the quality and the yield of sinter have been improved.
